' rods-6. To furtherreinforce the tank 2, at

its intermediate portion, a metallic band 7 is secured thereto;

.The tanlpQ-isprovided with a metallic slining, in the form of a deep .pan 8, having upwardly and outwardly flaring'sides that .terminate in an out-turned laterally projecting flange 9%t'hat overlies and is rigidly secured to-the upper edgepf thet-ank 2 by lag screws 10, or any-other suitable means. This pan 8 isvspaced apart from the tank 2 at its bottom and sidesto form achamber 11, the purpose of which will presently appear. v v

At its bottomg the pan 8 rests on 2. p111- rality of transversely extended bars 12,41;- curedtothe bot-toiri of the tank To-keep this pan 8 properly-spaced from the sides of the tank2, horizontally.extended bars 13, in .reotangular arrangement, are secured to the inner-upper-edge portionof the-tank 2 undo plurality-of vertically extended bars 14- are also secured to the tank Qandextending from the bars "13 to-t-he bottomof the tank 2.

Mounted in bearings .15, secured to and projecting above the ends of the frame 1 .is a horizontally extended Water supply .pipe provided Witha pluralityof longitudinally valined small perforations 17 in .its under side. F or :the purpose of delivering the .water from the supply pipe 16 .to the, pan 8 ina finely divided state, a sheetof wirenetsting 18 is .folded over the .pipe IG-and rigidly securedthereto by rivets 19. The horizontal edges of thisnettinglsdepends from the pipes l6,-directly above the longitudinal center of the pan 8. Obviously, the Water,

.asthe same is discharged through the opening .17, will follow .alongrthe wires oonstitilting the screen 118, and drop therefrom into the pan -8. By this slow ,process of deliveringthe water tothe pan 8, the-expansion ofthezice is largely overcome.

Inthe sides of the:tank 2 is formeda plurality of ;ports .20 swinging covers 21, pivoted to-the.sides.0f its tank 2. During the freezing process of the Waterin-the pan 8 the ports 20 are left open, to permit the cold air to freely circulate-through the chamber 11 in close-contact with its pan 8. ,For the purpose of.re-

leasing the formed ice cake from .the ;pan 8,

steam is introduced into chamber 11 through a rectangular steam piper22 mounted on the "bottom of the .tanrk2 within the chamber 11.

adapted to be closed by.

A plurality of small openings 23 is found in its steam pipe 22 and are so arranged as to deliver steam in 'all,directions within the chamber 11. To permit free circulation of air and steam within the chamber 11, the bars 12, 13 and 14: are each provided-with a multiplicity of notches or grooves 24:. The grooves 24 in the bars 13 permit the steam to come in contact with the flange 9 and-melt the ice therefrom. One end of the steam pipe 22 extends through one end of the tank 2, and, in actual practice, will be connected to a suitable steam' supply, not shown. Obviously, hot water may be used in place of steam. 7

For receivingthe formed ice cakes'from the inverted pan 8, as they are released therefrom under the, action of the heat, introduced into -the chamber 11, a receiving platform 25 is mounted directly under the tank 2. This platform 25 is, as shown, preferably made up of a lurality of laterally spaced longitudinal connected by cross bars 26. As shown in Fig. 3, the platform 25- is somewhat longer than the frame 1 and extends completely through both ends thereof. Guide strips 27 are secured to the two outer edges of the receiving platform 25 to prevent the ice cake from slipping laterally therefrom.

The lower ends of a pair of hoisting cables 28 are connected to one end of the receiving platform .25, by a pair of eye-bolts29, and the lower ends of a second pair of hoisting cables 30 are secured to the other end of said platform by a pair of eye-bolts 31. Located directly above the eye-bolts 29 and journaled in bearings 32 secured to the upper ends of two of the corner bolts of the frame 1, is a transversely horizontally extended Windlass shaft 33. To the intermediate portions of this. shaft 33 are secured the upper ends of the cables 28 and on which shaft they are arranged to be wound. Keyed or otherwise secured to one end of the shaft 33, outside of the frame 1, is a spur gear 34 that meshes with a spur pinion 35 secured to a short shaft 36 journaled in one of the bearings 32. A hand crank 37, for operating the windlass shaft 33, is secured to one end of the shaft 36. For holding the windlass shaft 33in different set positions, a gravity actuated lock dog 38 is pivoted to the frame 1, in a position for engagement with the teeth of the spur gear 34.

The upper ends of the cables 30 are secured to and arranged to be wound upon apair of Windlass drums 39 secured to opposite ends of the Windlass shaft 33. The intermediate portions of the cables 30 run.

over a air of guide sheaves 40 secured to two of t e corner posts of the frame 1, above the eye-bolts 29. The lengths of the cables 28 and 30 are such that when the platform 25 IS in its elevated position,

ass

y extended slats own by dotted lines in Fig. 3, the same extends in a true horizontal direction; but, when the platform is lowered, (shown by full lines in Fig. 3) one-end thereof is somewhat higher than the other,,to permit the easily slid therefrom. This change of the position of the platform 25, from its. raised to'its lowered position, is accomplished by the difference in the diameters of the windlass shaft 33 and the Windlass drums 39. Obviously, the cables 30 will unwind from the Windlass drums 39 faster than thecable 28-will unwind from the Windlass shaft 33. In Fig. 2 the platform 25 is lowered into a horizontal position and rests entirely on the cross lower end of the bars of the frame 1. In this position of the platform there would be a small amount of slack in the cables 30.

To prevent spreading of the intermediate portions of the tank 2 during the freezing process, the sides of said tank are temporarily tied together by a removable tie rod 41 having its ends bent laterally to form hooks. This rod loosely rests upon the upper edge portions of the tank ,2 with its hooked ends projecting downward outside of the said tank. Pivotally mounted on one of the hooked ends of thetie rod 41,- is a cam lever 42 adapted to engage the tank 2 as a base of resistance and todraw the other end of said tie rod onto the tank 2.

To facilitate the freezing process of the water is attached to the hollow trunnion 3 a fan for creating a forced circulation of the cold air through the chamber 11. The fan is indicated, as an entirety, by the numeral 43, and may be driven by any suitable means, not shown, and it may also be of any de sired design or make. The fan 43 is connected to the outer end of the trunnion 3 by ashort pipe 44: provided with an upwardly projecting branch pipe 45, which terminates in a lateral nozzle extension 46.

This nozzle extension 46 is arranged to di-- rect a portion of the cold air fromthe fan 43 to the water as the same drips from the screen 18 into the an 8., The cold air forced through the ollow trunnion 3' is discharged after passing through the chamber 11 through a port 47 in the opposite end of the tank 2. A cover 48 is rovided for the port 47 for the purpose 0 closing the same at the time the steam is turned into the chamber 11, for the purpose of releasing the ice cake.

The operation of the machine .may be briefly described as follows: Water is first are, of course, left open to permit the cold oeaaoa air to circulate through the chamber 11. After the ice cake is completely formed, the water is shutoif and the tank 2 given a onehalf rotation to invert the pan 8, as shown by dotted lines in Fig. 3. Then the platform 25 is elevated, by operating the crank 37, into a position also indicated by dotted lines in Fig. 3. In this position of the platform 25, the same extends completely across the upper end of the pan 8 and also engages the tank 2 to thereby hold the same against rotation. The platform 25 is locked in this elevated position by the engagement of the lock dog 38 with the spur pinion 34. The ports 20 are now closed, by the covers 21, and steam "turned into the chamber 11 a sufficient length of time to melt the ice cake where the same adheres to the pan 8. As soon as theice cake is released from the an 8, the same will drop onto the receiving p atform 25. The platform 25 is now lowered and the formed ice cake removed therefrom.

,As soon as the platform 25 is moved away from tank 2, the same will immediately turn, under the action of gravity, into an upright or filling. osition.
